When using the python interface, Kicad crashes with a segfault following refresh when a filled zone is added in some cases.
Following code is a minimal example reproducing the problem:
import pcbnew
from pcbnew import FromMM
board = pcbnew.GetBoard()
zone = pcbnew.ZONE_CONTAINER(board)
sps = pcbnew.SHAPE_POLY_SET()
chain = pcbnew.SHAPE_LINE_CHAIN()
chain.Append( FromMM(0.0), FromMM(0.0) )
chain.Append( FromMM(20.0), FromMM(0.0) )
chain.Append( FromMM(20.0), FromMM(20.0) )
chain.Append( FromMM(0.0), FromMM(20.0) )
chain.SetClosed(True)
sps.AddOutline(chain)
zone.SetOutline(sps)
board.Add(zone)
pcbnew.Refresh()
Interestingly, problem only occurs when the shape is square, i.e. when last chain append is to (0.0,20) as above. If changed to (0.1, 20), or omitted (to make a triangle) then it works fine. |
